G4 Powerbook Specs
The PowerBook G4 was a series of laptop computers that Apple, Inc. manufactured and sold between 2001 and 2006. The "G4" suffix stood for its PowerPC G4 chip, the fourth generation of 32-bit processors produced by Motorola and its former subsidiary Freescale. Additionally, the notebooks ran Apple's Mac OS X operating system. The PowerBook G4 is notable for being the last generation of Apple's PowerBooks, as the company phased them out in favor of the Intel chip-based MacBooks.

Sizes, Design and Processor Specs
-
During its production run, the PowerBook G4 had three screen sizes: 12 inches, 15 inches and 17 inches. The traditional finish was an aluminum body and a 77-key keyboard, although Apple offered a titanium 15-inch PowerBook G4. The processor's clock speed, which is the rate at which it carries out its basic functions, ranged from 400 megahertz (MHz) to 1.67 gigahertz (GHz).
Memory and Disk Drives
-
Each PowerBook G4 had two small dual in-line memory module slots (SO-DIMMs) that contained the laptop's random-access memory, or RAM. The computer came with 128, 256 or 512 megabytes (MB) of RAM, which was divided between the SO-DIMM slots. The PowerBook G4 used the first generation of Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) architecture, with a read-access speed of 100 or 133 MHz.
The hard drive space range was 10 to 120 gigabytes (GB), spinning at a rate of 4,200 or 5,400 revolutions per minute (rpm). Although most of the PowerBook G4s have optical drives that play (read) and record (write) on CDs and DVDs, a few versions of the notebooks --- particularly the original 15-inch model --- might lack the DVD writing feature.

Graphics and Screen Display
-
The early PowerBook G4s, produced in 2001 and 2002, had ATI Mobility Radeon graphics cards that shared between 8 MB and 64 MB of the computer's RAM. The later models, on the other hand, had graphics cards from the NVIDIA GeForce brand; they took up a RAM range of 32 MB and 128 MB of RAM. Although all PowerBook G4s use a TFT (Thin Film Transistor) matte LCD (Liquid Crystal Display) screen, the resolution varies: from 1024 by 768 pixels for a 12-inch to 1680 by 1050 pixels for a 17-inch.
Communications Specs
-
Each PowerBook G4 notebook had a built-in 56-kilobit-per-second fax/data modem and 10/100BASE-T Ethernet. Apart from the earliest 15-inch version of the laptop, the G4 also had standard AirPort, which is Apple's implementation of the IEEE 802.11 wireless protocol, or Wi-Fi. The computer's external interfaces included two USB ports, FireWire 400 connector, VGA (Video Graphics Array) or DVI (Digital Visual Interface) connector, and headphone and microphone jacks.
